It’s been shockingly easy, actually! I do relatively few orders (2 per month) and can get a record of my filled orders [0] on the day I know my buys will occur. I plug those automated buys into a spreadsheet where I maintain a record of my orders. That spreadsheet does a FIFO capital gains calculation, and I’m good to go. I must admit, I haven’t sold yet, so I may just be niave about how 2018 taxes will go! [0]: https://www.gdax.com/orders/fills/BTC-USD https://www.gdax.com/orders/fills/BTC-USD
